Filed: 1990-06-01
Abstract: PURPOSE:To stabilize address demodulation by providing the bit group of the large duty ratio of a dark part and a light part at the head of an address area. CONSTITUTION:The bit group I with the large duty ratio to the extent of 3:1 of the dark part and the light part is provided at the head of the address area of an optical card. Therefore, DC component variation K to occur at the time of rush from a non-signaling part J to a signaling part becomes large. The capacitor 6a of an AC coupling filter 6 can be charged quickly by large potential difference due to this DC component variation K, and charge is completed before at VFO data N succeeding to the bit group I. Accordingly, a low frequency variation period 0 after the filter due to the charge of a regenerative signal M is finished within the area of the bit group I, and at the VFO data N, harmful low frequency is never generated. Therefore, stable binarization can be performed at a binary level P. Thus, a stable digital regenerative signal Q can be obtained.

Title: Plasma x-ray exposure device
Inventor: KATO YASUO
IPC: H05G2/00
Filed: 1986-06-23
Abstract: PURPOSE:To enable the subscription of an extremely fine figure of submicron order, by controlling the number of times of discharge by using the added values of the exposure of X rays for a specific exposure object and putting the exposure of X rays within the range of permissible errors. CONSTITUTION:Measured values of exposure are added, and if the added value exceeds a set standard, discharge for a specific object is stopped. The input of X rays is converted into an electrical signal and then measured by integrating the electrical signal. Errors caused by noises can be decreased by making the time for determining the added value be delayed by proper time after X-ray generation, e.g., several microseconds in which the noises attenuate. Short pulses of X rays, which may cause a problem on the response time of the integration circuit, shall be integrated by a simple CR circuit. By performing sampleholding of the output of the integrated signal in a delay time sufficiently short compared with the CR time constant after the start-up of the integrated signal, the exposure of X rays can be easily measured with high precision.
